[Java] Class EncodingGroovyMethods

Method Detail

public static byte[] decodeBase64(String value)

Decode the String from Base64 into a byte array.

Parameters:

value - the string to be decoded

Returns:

the decoded bytes as an array

Since:

1.0

public static byte[] decodeHex(String value)

Decodes a hex string to a byte array. The hex string can contain either upper case or lower case letters.

throws:

NumberFormatException If the string contains an odd number of characters or if the characters are not valid hexadecimal values.

Parameters:

value - string to be decoded

Returns:

decoded byte array

public static Writable encodeBase64(Byte[] data, boolean chunked)

Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

Parameters:

data - Byte array to be encoded

chunked - whether or not the Base64 encoded data should be MIME chunked

Returns:

object which will write the Base64 encoding of the byte array

Since:

1.5.1

public static Writable encodeBase64(Byte[] data)

Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

Parameters:

data - Byte array to be encoded

Returns:

object which will write the Base64 encoding of the byte array

Since:

1.0

public static Writable encodeBase64(byte[] data, boolean chunked)

Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

Parameters:

data - byte array to be encoded

chunked - whether or not the Base64 encoded data should be MIME chunked

Returns:

object which will write the Base64 encoding of the byte array

Since:

1.5.7

public static Writable encodeBase64(byte[] data)

Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.

Parameters:

data - byte array to be encoded

Returns:

object which will write the Base64 encoding of the byte array

Since:

1.0

public static Writable encodeHex(Byte[] data)

Produces a Writable that writes the hex encoding of the Byte[]. Calling toString() on this Writable returns the hex encoding as a String. The hex encoding includes two characters for each byte and all letters are lower case.

Parameters:

data - byte array to be encoded

Returns:

object which will write the hex encoding of the byte array

Parameters:

data - byte array to be encoded

Returns:

object which will write the hex encoding of the byte array
